OCK Breakers or Crushers as a rule constitute the first step in 
the treatment of ore in milling and reduction plants. Two 
types of rock crushers are in universal use, — the standard 
tangular jaw crusher, and the cylindri ratory crusher. 

Both crushers act upon the principle of approaching and reced- 
ing jaw> which deliver crushing blows upon the material 
broken, and both types have their advantages on certain classes 
of material. They are fed with ore of mixed sizes up to the maximum 
diameter that the month or receiving opening can take, and they break 
a fairly uniform size, which latter is determined by the distance 
en the jaws, or the throat of the discharge opening. As the lar.ge size 
and irregularity of the rock generally precludes automatic Feeding, feeding

The breakers referred to in this bulletin are all of the intermittent or 
jaw t- of our own manufacture, and are illustrated and described in 

the following order: — Hercules-Blake, Dodge, Roll-jaw. and the Hutchinson. 

The Blake breaker in its original form was first patented in 1858, and 
was the first successful breaker of the jaw type, and it has held its place as 
the standard machine ever since, being manufactured by builders of mining 
machinery throughout the world, with various improvements, but still retain- 
ing the basic ideas of the early invention. The principle of the operation 
of this breaker is too well known to require a lengthy description; however, 
it may be said that it has the least movement and consequently the greatest 
leverage at the throat where the largest particles of rock are broken and 
consequently is capable of doing a greater amount of work with less consump- 
tion of power per ton of ore crushed than any other jaw breaker. The 
greatest movement of the jaw is at the discharge end. therefore an easy 
and free discharge of the crushed rock is permitted, for this same reason and 
also because the lower end of the jaw when opening is apt to allow larger 
pieces to occasionally drop through, a finely crushed and even sized product 
is not obtainable. 

The Dodge breaker on the contrary has the greatest movement at the 
throat where the largest particles of rock are broken and consequently exerts 
the least leverage where it has the hardest work to perform. This breaker, 
therefore, is not adapted to heavy work, and it does not have as large a 
capacity per HP as the Blake. Being essentially a fine crusher it produces 
a fine and even product owing to the fact that the jaws at the discharge end 
are fixed and do not permit large particles of rock to leave the jaws as in 
the case with the Blake breakers. 

The Roller Jaw breaker differs from either the Blake or Dodge breakers 
in that it is designed to handle a class of material that can not be 
economically broken by the first named machines. The Roller jaw breaker 
is essentially designed for breaking or crushing wet or sticky ores of a clay 
or talc character, being the only successful breaker on the market for this 
purpose. The movement of the jaw given by the eccentric shaft and the 
toggle produces at once a combined downward and forward movement, the 
roller being revolved with the material as it is fed and crushed between the 
die or roller and the shoe on its way to the discharge end. Reference is made 
to page 14 for additional information. 

The Hutchinson breaker illustrated on page 18 has an original and new- 
movement of the shoe and die producing an effect not found in any other 
breaker, in that the combined downward and forward movement alternate 
in an opposed position, resulting in a combined crushing- and grinding action 
on the rock fed to it. wdiile at the same time causing a positive discharge of 
uniform product. As a fine breaker it is nor equalled by the Dodge and is 
capable of larger tonnage in a given time with about the same consumption 
of power. 

The succeeding pages of this bulletin are devoted to descriptive matter 
concerning crushing rolls and revolving screens and grizzlies of our own 
manufacture and embraced under the title of this publication.

The i i principle of this machine is the same as has been in use 

an) years past, but a number of new and novel feature- have been added 
thereby greatly increasing its usefulness, and also placing it in a class dis- 
tinctly superior to other Blake (.'rushers which have been heretofore offered 
her manufacturers. One of the impovements is found in the toggle-plate 
in two halves, la] one another and riveted together. (See 

I ii illustration), During the operation of crushing the rivets are in 
shear, and while the number of rivets used and their size are proportioned 
to be amp . to withstand the --train of crushing hard quartz, yet 

in the event of any unusual obstruction, such as a sledge hammer findin 
way into the crusher, the rivet heads will shear off. causing the toggle-plate 
to collapse, thi ermitting the obstruction to pass through without 

damage to the crusher, tn the ordinarj types of crushers damage occurs and 
ently the front head, pitman or movable jaw yields to the strain and the 
breaker becomi The replacement of toggles is inexpensive and a 

small compared with the renewal of the important other parts of the 



A prime feature of these crushers is found in the Adjustable Toggle-Seat 
(see page 9) insuring an even bearing for the toggle at all times. 

It will be noted from the illustrations that we have greatly increased the 
thickness of the back and front heads of this crusher as compared with our 
earlier types, likewise the side frames and also retaining the excellent prin- 
ciple of sustaining the strain of crushing by four heavy forged Steel rods 
shrunk-in to the ends and securely held on the rear end by hexagon nuts. 




End view of "Hercules-Blake" C 



A means for adjusting the space between the jaws for regulating the 
size of the output, as well as taking up the wear is provided by the use of 
sheet metal shims, behind the rear toggle block, and also by using toggle plates 
of various lengths. 

The pitman is cast solid, as a cap at the crank-bearing is unsatisfactory. 
The adjustment for wear at this point is made by means of a gib and cotter- 
key with lock nuts and easily adjusted. The shoes and dies supplied on these 
breakers are of '•Adamantine Chrome Steel" and are made reversible end 
for end, the economy of which is at once apparent. The fly wheels are held 
by saddle-keys and set screws which permits them to slip in case of a sudden 
stop.

'Hercules-Blake" Special Crusher 

(TypeB) 

Built for extra heavy dutv 




A decade since when gyratorj breakers were popular and in aim 
universal demand Fi ger quartz mills and rock quarries of 

that period, the general impression held b\ mosf practical millmen pres 
a limited use of the jaw breakers for the future. 

After years of practical comparison and observation these opinions h 
reversed and of recent years jaw crushers have again regained 
and in many instances preference. Jaw crushers are today performing duties 
where the gyratory breakers were absolute failures. 

The Hercules-Blake "Special" Type B Crusher will disintegrate rock 
which cannot be handled in the ordinar) jaw breaker. Granite boulders 
smooth collides, hornblende-granite and the like yield easily to the 
power of this special breaker supplied as it is with steel pit man. cheek plate 
front and rear head and toggle seat. The shoe and die are either of "Ada- 
mantine" Chrome steel or of Manganese steel (see page 8 for further descrip- 
tion!. The crushing strain is carried l.\ 6 hammered steel tension

Some advantages found in Hercules-Blake Crushers 

In the illustration on the opposite page is shown an interchangeable, 
interlocking, sectional crusher shoe and die which was designed to obviate 
one of the most serious objections heretofore found in jaw type crushers, 
viz. : the waste of material in the solid type of shoe and die when only the 
portion worn required replacement. To better elucidate this paragraph, we 
have prepared the following engravings. 




Fig. 1 



Fig. 2 



Fig. i represents a new shoe or die of an older type of Blake breaker, 
and Fig. 2 a similar casting worn down and cupped so deep that large pieces 
of ore or rock are permitted to escape further crushing. As the wear is 
greatest in the middle ends of the surface, and not throughout the entire 
width, the worn shoe and the die may be set up until they practically touch 
at the edges, and still be so badly worn or cupped that a piece of rock much 
too large for its purpose will easily escape and destroy the usefulness of 
the breaker. The average wear of shoes and dies is 2$ per cent of the total 
weight when new. thus leaving 75 per cent to become discarded and of no 
further value. This defect does not occur in the interchangeable, interlocking, 
sectional shoes and dies. These are made in six sections, two upper, two 
middle and two lower. Being fitted and dovetailed together so that when 
the two countersunk head bolts through the middle sections are tightened, 
the whole six sections are securely interlocked in place. The two upper, as 
well as the two lower sections are interchangeable, being exactly alike, and 
these may be shifted, reversed and turned upside down as they become worn, 
until their usefulness is over. The two middle sections are interchangeable 
and may also be changed as becomes necessary, and worn almost entirely to 
the surface. Having briefly described this improvement, it will readily be 
ibserved that 85 per cent of the weight of the shoe and die can lie used before 
replacements become necessary. 



Self-aligning Toggle Seats and Plates 

The breakage of ordinary square toggle plates is due to the fact that it is 
practically impossible to make them bear evenly against the seats throughout 
their entire width. The unequal shrinkage of the frame castings, etc.. cause 
the toggle plates to bear at one or two points only, the result being broken 
plates and a consequent loss of time and money. As will be seen from the 
illustration on page 0. the Hendy self-aligning toggle seats are laid out on 
the arc of a circle, the plates being made t<> suit. The ends and grooves are 
ground true, so that they bear throughout their entire length and auto- 
matically compensate for any unequal shrinkage or change in alignment of 
crusher frame.

The "Dodge" Ore and Rock Breaker 




Made in three sizes 

The "Dodge" type of ore breaker is intended to be used where a finer 
and more uniform product is desired. This is accomplished by its peculiar 
construction, the movable jaw being pivoted at the bottom, and giving the 
greatest throw at the top, and a motion hardly perceptible at the bottom. 
The size of product is determined by the distance apart between jaws, this 
is regulated by inserting packing blocks on either side of jaw shaft boxes and 
securing by adjusting screws. 

The Hercules-Blake type is better adapted for large capacities and coarser 
crushing. 

These breakers are fitted with steel shoes, dies and cheek plates: also 
tight and loose pulleys, of dimensions given. The rated capacity are based 
on iJ-2 in. jaw opening.

"Roller" Jaw Crushers 

The above illustrates our design and make of the "Roller" Jaw Crusher. 
The principal advantage of this type of crusher is its adaptability for working 
ir sticky ores, or where fine crushing is desired. The movable jaw to 
which is attached the shoe is mounted upon a revolving eccentric shaft, which 
gives the movement to same. The ore being crushed between the shoe and 
revolving die. causes the die to make a slight forward movement at each 
stroke; a backward movement is prevented as the jaw ascends by a roller 
placed between the roll die and the frame. Arrangement is made for setting- 
up shoe as it wears, or for fine crushing. 

A scraper is also fitted so as to press against the entire width of r 
thereby cleaning same; the pressure against roll being regulated by lever 
and weight. 

Double fly wheels are used, fitted with slipping keys; also tight and 
pulleys. 

We manufacture the sizes given on following page. The prices are for 
crushers fitted with steel shoes and dies and steel cheek plates; also tight 
and loose pulleys as designated by list.

The "Hutchinson" Ore Crusher 

The Hutchinson Ore Crusher, while designed primarily as a tine breaker 
is also adapted for fairly heavy work, and may be used as a primary breaker 
in capacities up to 15 tons per hour. Its particular function, however, is fine 
crushing, and in this respect is unequalled by any other breaker. The char- 
acter of the movement is unusual in that there is no stationary jaw. Both 
jaws move simultaneously in such a way as to give a combined crushing and. 
grinding movement that speedily reduces the rock to the desired fineness. 

The crank shaft has a two-throw eccentric, and the jaws are yoked 
together by adjustable connecting rods. The movement is such that the jaws 
ach one another and then recede, and at the same time the back jaw 
has a slight upward and downward movement, giving a crushing and grind- 
ing action on the particles of rock and also crowds the product downward 
until it has finally been reduced to the required fineness and is discharged. 

As will be observed in the illustration, this breaker is quite proportion- 
and compactly designed. Adjustment of the size of discharge opening 
and also the necessary adjustments for compensating the wear are readily 
made by shortening up the connecting rods. This is accomplished by screw- 
p the nuts and tightening the lock-nuts on the rods provided for that 
purpose. The wearing shoe and die are reversible, end for end, in order that 
a maximum wear may be obtained before renewals are necessary. This 
breaker is particularly adapted for primary breaking preparatory to feeding 
into Cornish rolls, or centrifugal or roller mills, etc.. where a fine feed is most 
essential for satisfactory fine crushing; and as a secondary breaker following 
the Hercules-Blake or other primary breaker where stage crushing is 
employed.

Standard (Class A) Crushing Rolls 



The above illustration is of our Standard (Class "A") Crushing Roll, 
and we can refer to many that, have been in continuous operation for ten 
years without any expense for renewals other than roll shells. 

The journal boxes are of the ball and socket type, in order that the strains 
on the bearings may be equalized. The adjustable roll is carried on two 
swinging arms or journals pivoted at the bottom. Secured to the top ends of 
each of these arms is a heavy tension rod which is carried through the oppo- 
site end of the frame. These rods are made with an eye on the front end. the 
back end being made with thread and double lock nuts for adjusting. The 
roll shafts have keyed onto them the cast iron centers for the shells and which 
are carefully turned to a taper. The shells are made of chrome steel turned 
true on the face and bored on the inside to corresponding taper of shell cen- 
ters, and held in place by bolts. These are completely encased in a sheet iron 
housing and a cast iron feed hopper fits between rolls fitted with wearing 
plates. When required, an automatic swinging gate feeder may be supplied. 
The rigid roll is the main driver, and is fitted with the larger sized pulley, 
while the adjustable roll shaft is fitted with a smaller pulley. 

The capacity depends upon the speed and size to which the ore is to be 
crushed. These rolls are specially adapted for use in coarse concentration 
where coarse crushing may be adapted best for the cyanide or other methods.

Standard (Class B) Crushing Rolls 



The experience gained by many years in the production of high grade 
mining and milling machinery and a close observation of the actual perform- 
ance of our machines under stress of varying loads and adverse conditions 
have enabled us to discover mechanical limitations and gradually evolve a 
combination of strength, compactness and durability with maximum output. 

The STANDARD (Class "B") CRUSHING 'ROLLS, which emboch 
all the principles known to be correct for its type, together with the improve- 
ment which persistent investigation has proven most desirable, is unques- 
tionably superior to any crushing rolls we have yet produced. 

In the description following, the engineer or practical millman will readily 
appreciate the exclusive features incorporated in the design of these rolls and 
recognize the ease with which running repairs and substitution may lie made. 

The main frame is of heavy proportion, made in a single piece and de- 
signed with a view to absolute rigidity, the bearings of the stationary roll 
being cast as a part of the same piece. The base is planed to facilitate instal- 
lation.- The bearings or journals are of liberal dimension and provided with a 
thick lining of the best babbit metal. 

Special provision has been made for adjustment, both longitudinal and 
lateral, thus eliminating any unnecessary strain. The movable bearings are 
lucted and set in their supporting castings so that the roll shaft may 
accommodate itself to the accidental passage of an unusually hard substance, 
through either edge of the roll without subjecting the machine to a one- 
strain and a resulting serious injury.

W"«il CM UU 




The stationary roll 
shaft is provided with an im- 

d side adjustment which remains 
immovable under the jar of the machine. 
roll -liai't- are of the best quality of 
el and are also carefully turned. The roll 
shells are made of "Adamantine" Chrome Steel, turned true on the face, bored 
out tapering to fit the roll centers and held in place by heavy draw bolts. 

Each set of rolls is provided with one large pulley on the stationary roll 
shaft and one small pulley on the movable shaft. The pulleys are made with 
clamp hubs and are additional!;, fitted with a key, thus insuring a most rigid 
attachment, though easily removed for repair. 

The aver.:. tance to crushing is probably less than 5,000 pi 

pressure. This pressure is purely variable and will rise much higher than 
the above figure or fall to nil, according to rate and size of feed. 

An even pressure is sustained by two main tension bolts provided with 
eight heiical springs, whose limit of compression is ascertained by actual 
hydrostatic pressure. The springs yield only when the resistance to crushing- 
reaches their limit of compression. Between the faces of the movable bear- 
ings and the collars of the tension rods are interposed removable shit 
varying thickness, by means oi which, with the desired am. Mint of compres- 
p ings, the distance between th( roll faces maj be maintained at 
a fixed minimum, and the rolls never come together, even when running 
without ica\. 

The tension rod nuts are of the special clamp type and will not jar 
The upper housing for the rolls is made of cast iron to fit the lower housing. 
'Ihese cast iron sides are finished on the bottom, to make an accurate joint 



with the frame. The. remaining section over the rolls is provided with a 
flexible heavy duck or canvas cover having- heavy wooden strips to hold it in 
place. On the top of the housing there is placed centrally a cast iron receiv- 
ing hopper, through which the material is fed to the rolls.

Flanged Roll Shells 




bove is an illus i air of flanged roll shells de- 

! and used by the Lassen Mining Company at Haydenhill, Cal. 
This particular type of flanged shell has been in successful opera- 
nd the addition of the fl; 
has increased thi rtt. One set of these 

flanged shells, made of Mang i I. has crushed 30,000 tons ol 

irdina shell without the flangi 

i not crush more than 15,000 tons bi Fori it became n 
ace them. 



The corrugation of roll shells, largel} caused by side thrust of the float- 
ing -haft, has been practically overcome by the use of a double flanged shell 
on the driven roll. 

On certain types of crushing rolls this side thrust has been so great that 
before the shell had performed half its work, only sixty per cent of the face 
of the shell was in use — the side thrust and corrugations causing a flange to 
ide of the shell, making the crushing surface uneven, and leav- 
ing the shell in the form of a flanged ear wheel. 

By using a double flanged shell on the floating shaft, as shown in the 
accompanying illustration, the side thrust has been entirely eliminated, the 
shells \v#ir even and true and the corrugations are reduced to a minimum. 

Shells of this type that have been in constant use for six years have 
increased the efficiency of the crushing rolls fifty per cent since their adoption. 




"Special" Re-Crushing Rolls 



Here is illustrated what we have termed our special design of re-crushing 
rolls; these are of lighter design and construction, to be used where the duty 
is not as severe as where the "Standard" are employed. Several are in use for 
disintegrating dried tailings, preparatory to treatment by the cyanide process 
or where a limited amount of ore is to be crushed very fine, as in sampling 
works. The roll faces are generally turned and ground to give a perfect con- 
tact between them. 

The general construction is - shown by cut and consists of two side 
frames, tied together cross-wise by through bolts and thimbles, and the 
upper side lengthwise with through bolts. The rigid roll is supported by 
bearings, the lower half of which is cast with frames. The movable roll is 
supported by bearings fitted to a guide in bottom of frames and adjusted by 
means of heavy screws and lock nuts and springs, for adjusting it to such size 
of crushing as may be desired, and to relieve any undue pressure upon rolls. 
A cast iron feed hopper is placed between rolls. 

The roll centers and shafts are cast together, the center being turned to 
a taper and the cast steel shells are bored to fit same and secured by cross- 
bolts. With these, both rolls are fitted with the same diameter and face of 
driving pulleys, and are not fitter', with sheet iron housing.

Revolving Rock Screen or Trommel 



This type of construction embodies the latest ideas and improvements on 
this class of machinery and is the most satisfactory design that can be em- 
ployed for the purpose. The feed end is fitted with a cast iron throat on 
which a tire is mounted, which reoJves in two rollers. The feed throat ex- 
tends far enough beyond the rollers to prevent the dust from getting into the 
roller bearings. The discharge end of the screen, as will be seen in the illus- 
tration, is free from obstruction, the driving mechanism being located at this 
end, the gear being cast on a cast iron plate, and this plate being the same 
diameter as the screen itself. 

The driving gear is fastened to the screen with four pieces of heavy 
channel steel extending throughout the entire length of the screen and 
securely bolted to same. The driving mechanism extends beyond the point 
of screen discharge and is fully protected against grit or dust. 

The screen may be fitted with or without right angle drive, to suit in- 
dividual requirements. 

The screen proper is made of steel plate with holes punched or drilled to 
suit conditions of purchasers.
